Alright wake up and smell the coffee cuz I'm tired of seeing this debate go in circles without any actual data everyone just parrots what their provider says but I just spent all night running my scrapers through both methods with three different proxy types and you're gonna want to see these results Set up a test scraping a dummy ecom site with a simple script rotated every 100 requests used the same geo-targeted residential pool from a major provider you know the one first run with username-password authentication in the proxy config second run with my server IP whitelisted in their dashboard and just using IP auth track it or lack it right User-pass on residential gave me an average request time of 2.1 seconds with a 12% timeout rate on mobile proxies it was even worse at 3.4 seconds and 18% timeouts switched to IP whitelist residential dropped to 1.4 seconds timeouts at 3% mobile dropped to 1.9 seconds timeouts at 5% datacenter proxies showed less difference but still a consistent half-second improvement with whitelisting that's not margin of error that's your scraper actually finishing the job The reason is obvious when you think about it every request with user-pass has that extra handshake overhead for authentication the proxy server checks your credentials before routing your traffic with IP whitelist it sees your server's IP on the allow list and just lets it through no extra steps it's like having a bouncer check your ID at the door versus walking into a private party where they already know your face one is faster and fewer things break So can we please stop pretending this is just a preference thing if you're doing anything at scale where speed and reliability matter like scraping social media or sneaker bots you need to be using IP whitelist yeah it's less flexible if your server IP changes but that's what static IPs are for set up a cheap VPS with a dedicated IP whitelist it and never look back user-pass is for small-time stuff or when you're literally working from random coffee shops otherwise you're just adding friction for no reason
